Publication Metadata only Verrucous Bowen’s disease on groin with dermoscopic and siascopic images(2017-05-06T00:00:00Z) CENGİZ, FATMA PELİN; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEPublication Open Access Dermoscopic Features of Small, Medium, and Large-Sized Congenital Melanocytic Nevi(2017-02-01) Cengiz, FATMA PELİN; Emiroglu, NAZAN; OZKAYA, Dilek Biyik; Onsun, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEBackground: Congenital melanocytic nevi (CMN) are present at birth. It is well known that the presence of large-sized congenital nevus in early life could predict a major risk of developing melanoma. Objective: To investigate the clinical and dermoscopic features of the CMN, to search for and highlight any differences between small-sized, medium-sized, large-sized CMN. Methods: A nonrandomized observational study was performed. A total of 108 melanocytic nevi were analysed by clinical and dermoscopic examination. Results: Of the subjects, 57.4% were aged less than 16 years, 42.6% were aged 16 and more. Of the nevi, 26 had reticular pattern (24.1%), 35 had globular pattern (32.4%), 13 had reticular-globular pattern (12.0%), 16 had homogeneous pattern (14.8%), 6 had reticular-homogeneous pattern (5.6%), 2 had globular-homogeneous pattern (1.9%), 7 had cobblestone pattern (6.5%), 3 had reticular patchy pattern (2.8%). Atypical dots and globules, focal hypopigmentation and perifollicular hypopigmentation are the most common dermoscopic features of CMN. The rarest dermoscopic feature is the blue-whitish veil. Conclusion: Most of the dermoscopic features related with dysplastic nevi up to the present, such as atypical dots and globules, focal hypopigmentation, perifollicular hypopigmentation were observed in CMN, in our study. Congenital nevus and dysplastic nevi may share the same dermoscopic features, therefore it is important to know it is found at birth or not.Publication Metadata only Verrucous Bowen’s disease on groin with dermoscopic and siascopic images(2017-05-06T00:00:00Z) CENGİZ, FATMA PELİN; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEPublication Open Access Frequency and risk factors for secondary malignancies in patients with mycosis fungoides(2016-08-01) EMIROGLU, NAZAN; CENGIZ, F. P.; BAHALI, A. Gulsel; Su, O.; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEMycosis fungoides (MF), the most common form of cutaneous T-cell lymphoma (CTCL), has an incidence of 6.4 per million people [1]. Patients with CTCL have an increased risk of the development of secondary malignancies, particularly lymphomas [2,3]. We conducted a 20-year population-based cohort study to assess the risk factors of secondary cancers in MF patients from our center.Publication Metadata only Hafif ve Orta Şiddetli Akne Hastalarında A ve E Vitamini Düzeyleri(2017-04-01T00:00:00Z) CENGİZ, FATMA PELİN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEPublication Metadata only Alopesi areatanın patogenezinde dehidroepiandrosteron sülfatın yeri(2017-04-15T00:00:00Z) EMİROĞLU, NAZAN; CENGİZ, FATMA PELİN; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; EMİROĞLU, NAZAN; CENGİZ, FATMA PELIN; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEPublication Metadata only ALOPESİ AREATANIN PATOGENEZİNDE DEHİDROEPİANDROSTERON SÜLFATIN YERİ(2017-04-15T00:00:00Z) EMİROĞLU, NAZAN; CENGİZ, FATMA PELİN; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; EMİROĞLU, NAZAN; CENGİZ, FATMA PELIN; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEPublication Metadata only Akneli Adolesanlarda Kardiyolojik Risk Faktörleri(2017-05-14T00:00:00Z) CENGİZ, FATMA PELİN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; BIYIK ÖZKAYA, DİLEK; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; BIYIK ÖZKAYA, DİLEK; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEPublication Open Access Dermatoscopic findings of pigmented purpuric dermatosis(2016-09-01) Su, Ozlem; OZKAYA, Dilek Biyik; Emiroglu, NAZAN; Cengiz, FATMA PELİN; Bahali, ANIL GÜLSEL; Yildiz, PELİN; DEMIRKESEN, Cuyan; Onsun, NAHİDE; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM; CENGİZ, FATMA PELIN; BAHALI, ANIL GÜLSEL; YILDIZ, PELİN; ONSUN, NAHIDEackground:: Pigmented purpuric dermatosis is a chronic skin disorder of unknown aetiology characterised by symmetrical petechial and pigmented macules, often confined to the lower limbs. The aetiology of pigmented purpuric dermatosis is unknown. Dermatoscopy is a non-invasive diagnostic technique that allows the visualisation of morphological features invisible to the naked eye; it combines a method that renders the corneal layer of the skin translucent with an optical system that magnifies the image projected onto the retina. Objectives:: The aim of this study is to investigate the dermatoscopic findings of pigmented purpuric dermatosis. Methods:: This study enrolled patients diagnosed histopathologically with pigmented purpuric dermatosis who had dermatoscopic records. We reviewed the dermatoscopic images of PPD patients who attended the outpatient clinic in the Istanbul Dermatovenereology Department at the Bezmialem Vakıf University Medical Faculty. Results:: Dermatoscopy showed: coppery-red pigmentation (97%, n = 31) in the background, a brown network (34%, n = 11), linear vessels (22%, n = 7), round to oval red dots, globules, and patches (69%, n = 22; 75%, n = 24; 34%, n = 11; respectively), brown globules (26%, n = 8) and dots (53%, n = 17), linear brown lines (22%, n = 7), and follicular openings (13%, n = 4). Conclusion:: To our knowledge, this is the first study to report the dermatoscopy of pigmented purpuric dermatosis. In our opinion, dermatoscopy can be useful in the diagnosis of pigmented purpuric dermatosis.Publication Metadata only Malignant melanoma arising in congenital melanocytic nevi: clinical and dermoscopic challenges(2017-01-01T00:00:00Z) CENGİZ, FATMA PELİN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDE
